(fhandler_base::fhandler_base): Ditto. (fhandler_base::close): Handle overlapped I/O structure if appropriate. (fhandler_base::dup): Ditto. (fhandler_base::fork_fixup): Ditto. (fhandler_base::setup_overlapped): Define new function. (fhandler_base::destroy_overlapped): Ditto. (fhandler_base::wait_overlapped): Ditto. (fhandler_base::read_overlapped): Ditto. (fhandler_base::write_overlapped): Ditto. * fhandler.h (fhandler_base::get_overlapped): Declare new function. (fhandler_base::setup_overlapped): Ditto. (fhandler_base::destroy_overlapped): Ditto. (fhandler_base::wait_overlapped): Ditto. (fhandler_base::read_overlapped): Ditto. (fhandler_base::write_overlapped): Ditto. (fhandler_base::get_guard): Eliminate. (fhandler_pipe::*): Rework to eliminate most Win9x related cruft, removing many variables and defining a new overlapped capability. (fhandler_fifo::*): Ditto. (fifo_state): Declare new enum. * fhandler_fifo.cc (fhandler_fifo::fhandler_fifo): Remove old Win9x stuff. Initialize overlapped handle to NULL. (fhandler_fifo::set_use): Eliminate. (fhandler_fifo::open_nonserver): Define. (fhandler_fifo::open): Rework to use named pipes and overlapped I/O. (fhandler_fifo::wait): Define new function to wait for named pipe connection. (fhandler_fifo::read): Rework to use wait() and new overlapped I/O functionality. (fhandler_fifo::write): Ditto. (fhandler_fifo::dup): Eliminate. * pinfo.cc (commune_process): Remove fifo handling. (_pinfo::commune_request): Ditto. * pinfo.h (picom): Ditto. * pipe.cc (fhandler_pipe::fhandler_pipe): Remove Win9x stuff. Initialize overlapped handle to NULL. (fhandler_pipe::open): Eliminate Win9x stuff. (fhandler_pipe::set_close_on_exec): Eliminate. (read_pipe): Eliminate. (fhandler_pipe::close): Ditto. (fhandler_pipe::fixup_after_exec): Ditto. (fhandler_pipe::fixup_in_child): Ditto. (fhandler_pipe::read): Rework to use overlapped I/O. (fhandler_pipe::write): New function using overlapped I/O. (fhandler_pipe::dup): Rework to eliminate Win9x stuff. (fhandler_pipe::create_selectable): Rework to eliminate Win9x and use overlapped I/O. * select.cc (peek_pipe): Rework to eliminate Win9x stuff and use overlapped I/O. (fhandler_base::ready_for_read): Ditto. --- winsup/cygwin/pinfo.h | 11 +++++------ 1 file changed, 5 insertions(+), 6 deletions(-) (limited to 'winsup/cygwin/pinfo.h') diff --git a/winsup/cygwin/pinfo.h b/winsup/cygwin/pinfo.h index 95e8d2617..b6b46e6b8 100644 --- a/winsup/cygwin/pinfo.h +++ b/winsup/cygwin/pinfo.h @@ -24,12 +24,11 @@ enum picom { PICOM_EXTRASTR = 0x80000000, PICOM_CMDLINE = 1, - PICOM_FIFO = PICOM_EXTRASTR | 2, - PICOM_CWD = 3, - PICOM_ROOT = 4, - PICOM_FDS = 5, - PICOM_FD = 6, - PICOM_PIPE_FHANDLER = 7 + PICOM_CWD = 2, + PICOM_ROOT = 3, + PICOM_FDS = 4, + PICOM_FD = 5, + PICOM_PIPE_FHANDLER = 6 }; #define EXITCODE_SET 0x8000000 -- cgit v1.2.3
